ranked in productiveness by a number of sorts. Beseler I gave the lowest yield of 

 grain, but with Strube ranked firs! in all years in straw production. Anderbeck and 

 Selchow side oats were also heavy yielders of straw, while Selchow Panicle, Fichtel- 

 gebirg, Probstei, and Beseler III Btood last in this regard. 



A high percentage of grain was produced by Selchow Panicle, Beseler III, Duppau, 

 Leutewitz Yellow, Probstei, and Beseler II, and a l"\\ percentage bj Selchow side 

 oats and Beseler I. Beseler 11. Strube, Anderbeck, Probstei, and Duppau produced 

 the heaviest grain, and Heine Trauben, Fichtelgebirg, Selchow Bide oats, and espe- 

 cially Leutewitz Yellow, the lightest. The liter weight of the grain varied consider- 

 ably in different years and was quite irregular. Leutewitz Yellow and Beseler 111 

 were lowest in percentage of hull and Beseler II, Strube, and Fichtelgebirg highest. 



The grain of Beseler I, Selchow side oats. Anderbeck, and Beseler II was richest 

 in protein, while that of Fichtelgebirg and Leutewitz Yellow was poorest. Selchow 

 side oats and l.eutew it/. Yellow outranked all other varieties in the fat contenl of the 

 grain, and Leutewitz Yellow also ranked first in ash content. < >n the average, Fich- 

 telgebirg ripened earliest, hut showed the greatest tendency to lodge. Duppau, 

 Strube, and Heine Prolific stood up well, and Selch-.w Panicle apparently produced 

 the strongest straw. The Beseler varieties, together with Leutewitz Yellow, Heine 

 Trauben, and Strube, proved quite smut-resistant. 



The strong stooling varieties were Fichtelgebirg and Leutewitz Yellow, and the 

 weak stooling soils Strube, the Beseler varieties, Heine Prolific, and Selchow Panicle. 

 The Beseler varieties produced the longesl straw, and Fichtelgebirg, Strube, and 



Leutewitz Yellow the shortest. Anderheck, the Leseler oat-, and Struhe were char- 

 acterized in comparison with the other varieties by thick stem-. 



A preliminary report on growing- Irish potatoes, ( '. M. Conneb | Florida Sin. 

 Bui. 8$, />/>. 387-406, pis. 4). — A brief discussion of potato culture in Florida is given 

 and the results of experiments in 1905 are tabulated but no conclusions are drawn 

 from the data. The work consisted mainly of fertilizer tests to determine the best 

 sources and the hest quantities of the essential plant food elements. 



Of different varieties tested Rose No. 4, grown from blossom ends, yielded 215 bu. 

 and grown from stem ends, l , l > o hu. of marketable potatoes per acre. These were 

 the heaviest yields secured. This same variety grown from Massachusetts seed 

 yielded 1(50 hu., from Virginia second-crop seed L79 bu., and from seed grown at the 

 station during the previous fall from small potatoes left from the spring crop. 89 bu. 

 per acre. 



Some results of potato investigations in 1905, T. ( '. Johnson | [Quart.'] Rpl. 

 W. Va. lid. Agr., 1 i 1906), pp. $1-50). — Potato culture as carried on in West Virginia 

 in the counties bordering on the Ohio River is described with reference to its extent 

 on the bottom lands along the river, the fertilizer applications and crop rotation. 

 the soil and its preparation, planting and cultivating the crop, harvesting and 

 marketing, and the attacks of fungus diseases. 



The principal varieties grown are EarlyOhio, Carmen No. L Carmen No. 2, Green 

 Mountain, and sir Walter Raleigh. Experiments in spraying with Bordeaux mix- 

 ture indicated that this was a profitable operation, a marked gain being shown in 

 the production of the highest grade of tubers. With reference to that part of the 

 crop consisting of small tnhets spraying was unprofitable. 



A rough skin in its relation to the starch content of potatoes, K. Kk/v.mowski 

 | Jour. Landw., 54 {1006), N<>. /, pp. 57-64)> — Work on this subject by different investi- 

 gators is reviewed and the author's ow n results are presented. The rough and smooth 

 skinned tubers of 15 different varieties were analyzed and in 14 cases the rough-skinned 

 tubers were richer in starch. The starch content of the smooth-skinned potatoes 

 ranged from 16 to 19.2 per cent and that of the rough from 17.1 to 21.6 percent.
